GPS unit

I'm looking for a (cheap) GPS unit for my holiday in Africa. The only thing it should do, is record coordinates and save waypoints (about 100-200). With these coordinates, place my photos on Google Earth, so everyone can see where those pictures were taken.

I do have a iPaq handheld with GPS software and a separate GPS mouse, but this combination is a bit fragile, so I need something more solid.

Minimum requirements:

• Lot's of batterylife (preferably an accu instead of loose batteries)


• Compass


• Altometer


• Waypoints


• Not too heavy


• PC interface (preferably USB and Mac compatible) for downloading the data.
